LANTERN;

Application filed September 21, 1922. Serial No. 589,666.

To all whom it may concern:

Be it known'that I, FREDERICK W. VAN DUYN, a citizen of the United States, residing at New York, inthe county of New York and State of New York, have invented a new. and useful Improvement in Lanterns, of which the following is aspeeification.

This invention relates to lanterns of that kind in which the glass globe is detachably retained in place on the globe plate or support by a wire globe-protecting guard which bears with spring pressure againstthe globe. In some lanterns of this sort in-which the globe plate is hinged to the lantern frame,

' the globes have been provided with shoulders or projections for engagement by the guard wires for the purpose of holding the globe firmly on the globe plate and preventing it from shifting-or falling when the globe plate and globe are tipped back for exposing the burner, removing the globe or for other If the vwire guards in such lanterns are proportioned so as to bear on the shoulders or projections with sufiicient force 'to hold the globes firmly and stationarily on the globe plates. the wire guard will not always springinto holding engagement with the shoulders or projections simply by shoving the globe endwise into position on the globe plate or support, but

it is frequently necessary to lift the guard wires by hand onto the holding projections or shoulders. It has also been proposed heretofore to make the globes with-segmental projections or portions on the opposite sides thereof intended to be engaged with and disengaged from the Wire guard by turning the globe on the globe plateorsupport, but with such aconstruction more or less care is required to see that the globe is not turned so far as to move the knobs or projections out of holding engagement with the wire guard, and if the globe should be accidentally turned on the globe plate or support out of the intended position, the

globe will not be held, and is apt to be dis placed and broken. Furthermore, in globes of this sort heretofore made, the projections have been of such form that they do not always insure the proper engagement of the guard Wires with the projections by the turning of the globe on the globe plate, and it is frequently. necessary to lift the guard wire by hand into engagement with the projections.

The object of this invention is to over-- come the obj eotions to theconstructions heretofore known, and to provide a globe having a holding shoulder and guard-engaging pon tions or projections, so constructed as to insurethat the guard-can be properly engaged with the holding shoulder; of the globe simply by moving or turning the globe, and. will hold the glo e firmly, andso as to prevent the releasing of the globe in the event that the same should be accidentally turned on the plate or support to a position in which the guard-engaging projections or portions of the globe are not inlalinement with the holding portions of the guard.

In the accompanying -drawings: V t Fig. 1 is a front elevationof a tubular lantern provided with globe holding means embodying the invention.

Fig. 2 is a side elevation thereof showing. the globe and globe plate tipped back.

Fig. 3 is a fragmentary side elevation of the globe and guard showing the camming position of the cam projection When lifting the guard wire.

Fig. 4 is a similar view-showing the holding position of the parts-- i *ig. 5 is a horizontal section of the globe. Figs. 6and 7 are'fragmentarysections of the globe on lines 6-6, and 77 respectively, Fig. 5. v

A represents the oil pot, B the tubes,'C the top, D the spring pressed chimney or globe,-

holder, E theglobe lifting; shaft, F the hinged globe-supporting plate, and G the type. The globe supporting plate, as usual, is connected to the lifting shaft by a suitable hinge f which permits the globe plate to swing rearwardly from its normal position over theburner. The globe guard may be of any usual or suitable, construction, the guard shown being of the well known cross wire type, in which two oblique wire bows 10 cross each other at the front'and rear sides of the lantern and have bent top portions adapted tobear against the holding shoulder or projections on the globe.

The globe is formed with a circumferential, external shoulder or offset 11, which preferably extends completely around the globe at a point betweenthe ends of the, globe, such that the upper portions of the guard wires are adapted to bear on the shoulder at opposite sides-of the globe for globe guard of a tubular lantern of known holding the globe'in place on theglobe plate F. At its opposite sides the globe is also provided with two guard-engaging projections or portions '12, which extend upwardly on the sides of the globe from points below the circumferential shoulder 11, and terminate at their tops at or substantially at the site sides of the globe and extend only a" comparatively short way around the globe so that the globe can be placed within the guard on the globe plate F, with the projections 12 located between the converging upper portions of the guard wires.

By placing the globe on the globe plate in this position, and then turning the globe partway around. in either direction on the globe plate,-the diverging edges13 of the projections will. engage the opposite portions of the guard wires and act as cams to lift the guard wires up onto the tops of the projections or onto the circumferential shoulderYlQ, which is preferably coincident with the tops of the projections. guard wires have been thus engaged with the circumferential shoulder 11 it is not necessary, for the globe to remain in a position in which the projections 12 are alined with the top portions'o'f the guard, but the globe can be turned to any position on the globe plate]? and the guard wires will remain in engagement with the circumferential shoulder and securely retain the globe in position outhe globe plate irrespective of the position to which the globe may be turned. The projections 12. being, as explained, of wedge shape, the globe can be pushed straight down into the guard and if the position of theglobe is such that the projections engage the top portions of the guard wires the wires will ride up on the projections, and in many instances, will snap over the tops of the projections. But it the guard fails to be moved into holding engagement with the projections in this way,

After the then; by turniii'gthe globe, as'zexplai'ned, the projections act as cams to move the guard wires into holding engagement with the circumferential shoulder 11, and thereby insure the proper fastening of the globe,not-

withstanding that the upper portions of the guard wires may, and preferably do, normallystand below the tops of'the projections to insure a very firm pressure of the.

globe downwardly upon the globe plate. After the engagement of-the guard wires with the tops of the projections or the shoulder 11, the globe cannot he accidentally moved out 0t holding engagement with the guard by the accidental turning of the globe to a position in which the projections 12-, are moved from beneath the holding upper portions of the guardwiresr I I claim as my invention:

1. In combination in a lantern, a globe supporting plate, spaced holding members thereon arranged to bearagainst the globe. and a globe having a circumferential shoulder arranged to be engaged-by said holding members for. holding the globe on the supporting-plate, and said globe also from said shoulder and are adapted by turning the globe to engage said holding mem;

bers to move the same intoholding engage. ment with said shoulder.

. 2. The combination of a globe supporting plate, a globe guard thereon having holdingportions which partially encirclec a'n' d bear against the globe, and a globe ,ha'ving'a continuous shoulder which completely encircles the globe and is arranged tobe engaged by said holding portions of the guard for'hold-' ing the globe on' the globe plate, andv said globe also having cam-like pOrtionscooperating with said shoulder and adapted vby turning the globe-to, engage said holding portions. of the guard and move the same into holding engagement with said shoulder.

33. A lantern. globe having a circumferhaving cam-like portions which diverge
